The term was revived in the 1960s by Chicano ethnic group MEChA to refer to Latinos in the United States and the people in Mexico as a unified "race",
similar to the black and white races. In this sense it is largely
synonymous to the notion of the Chicano nation. The decision to call it a
separate "race" may have been influenced by the contemporary
negative views of "ethnic" or "nation" based nationalism and
positive views of "race" based nationalism. The notion was first
enunciated in the Plan
Espiritual de Aztlan document.
